Thanks for checking, Mike. I'm actually doing this (omitting #:parameter-type), 
but then, when I run the application and interact with something in the GUI 
that should trigger an action, I get the following error, and the appropriate 
callbacks are never run:

I thought that maybe this could be related to not specifying 
#:paramenter-type... So I don't understand what I'm doing wrong. This is the 
application I'm trying to write:

https://gitlab.com/luis-felipe/geteka/-/blob/master/geteka.scm

The actions and connections are defined in the "app:activate" and "app:startup" 
procedures.
